Question / Help FPS drops/Lag ingame

[carecry]

Hi,

I've been trying to stream while playing Quake or Overwatch, any FPS game for that matter without any lags. I have an i7 4790k overclocked to 4.5ghz and according to OBS and my task manager, OBS is only using 10% of my CPU with veryfast preset and 2500bitrate on x264. I also have a solid 9mbps upload.

Everything looks like it should work? I've tried Quick Sync, I've tried OBS Studio and OBS Classic, I've tried updating drivers, and I've tried lots of different settings. There must be something I'm missing because in theory I shouldn't be getting this problem :s

Log itself is not so bad. This is your first run? We have some guides there: https://obsproject.com/forum/resources/categories/guides.2/

Not my first run no. I've done a lot of attempts. Its just that it feels very "laggy" ingame, as if my connection is being and I also get some fps drops. When recording locally there's no problem though, it seems to be network related, but I'm streaming at 2k bitrate and have 9mb upload so I don't really know what to do!

Try different service, like youtube for example.

I tried that, didn't work.

I've made a little progress though - by disabling visual affects on Windows 10 I've been able to remove the feeling of input lag. Also I've found that if I stream under 1.5k bitrate it doesn't lag me in game. I've put through an upgrade to my upload from 9mb to 19mb, hopefully that'll let me stream at 2k without lagging ingame.

Thanks for your help so far, I might post my results afterwards. Might have to do something to improve CPU usage also because although Quake Live doesn't use much, Overwatch is eating my CPU

2 thoughts after looking at your log, only 4 gigs of system ram on windows 10 trying to game and stream. Another is that you are using opengl instead of directx 11 for renderer( check settings->advanced). 9Meg is more then enough for a 2k stream

I have 16 gig of RAM. 2x8GB sticks in dual channel as shown in CPU-Z. Not sure why it says I have 4GB, unless that's my GPU RAM. I think actually its because of 32-bit OBS that only detects up to 4gb of RAM. But I've tried the 64-bit OBS and it still does the same thing :)

I'll try again when I get home and post a new log. I might have 19mb upload by then though :)

@carecry having a lower Upload wont create the ingame to be laggy that's usually more related to Ram, CPU or GPU being pushed to its max and above.

Looking at the logs your pc should be fine with the settings you are using, but can you confirm the cpu % when steaming? failing this have you tried Nvenc to see if you get the same issues? or 64bit OBS though it should be fine with 32bit.

CPU usage is only at roughly 30-50% when playing Quake Live and streaming, I have got an i7 4790k at 4.5ghz after all. I've tried Quick Sync also and I still had the same lags just worse quality on the actual stream. I'll try Nvenc as well. I have mainly been using 64-bit OBS and that's the one I've been testing with now. I'll try again when I get home and post logs. I do feel even the slightest lags tbh, but these are an FPS drop by about 30 and it feels like I have a huge lag spike where the game freezes for a second or two, and when it starts happening it happens roughly every 5-10 seconds. I want to be playing competitively while streaming, so this isn't acceptable for me. Really weird, but I think it has to do with the buffer size and bitrate because my PC is performing fine as far as I can tell, and the lags don't occur at all when I stream at a low bitrate of ~1.3k.. we'll see I guess?
